mzome Patented Mar. 25, 1930 ITED.-' STATES- PATENT orrlca RICHARD UHLIG, OF BETHLEHEM, PENNSYLVANIA DEVICE FOR WEIGHING MATERIAL DURING ITS IIO'IION THROUGH A CONVEYIB Application filed J'uly 15, 1927, Serial No. 206,104, am1 in Germany December 19, 1925.

This invention relates to ade'vice for weighing material, especially granular material, during its motion throu h a conveyer which is provided with a trafvelling'belt-serving for 5 supplying the material to the weighing device proper as well as for discharging it therefrom, and consists essentially therein, that the weighing device and the reversing rollers of said belt are arranged displaceably in the direction of travel of the belt, in order to be able to adjust at will the position .of the places where the weighing of the material and its discharge from the weighing devices takes place,

A further feature of my inventionconsists therein, that the weighing device and the reversing rollers for the travellin belt are mounted'upon a common travelling frame and that said frame is constructed as a carriage for discharging the material from the conveyer.

There are devices known for the weighing of granular material or the like-during its being conveyed by a conveyer, said devices 'employing one and the same travellin belt for supplying said material to and disc arging it from the weighing device, in such a manner that the material is carried below an automatic balance or the like and around the 0 same by mans of reversin rollers. According to my invention the we1ghing and eventually also the dischargin of the material may be accomplished at di erent points of the travelling belt, for instance by mounting the 5 weighing device and the reversing rollers for the travelling-belt upona common travelling frame, said travelling frame being at the same time constructed to serve as a discharge carriage, which may be positively moved in for- 40 ward and backward direction.

The material therefore may either be discharged onto the continuously travelling belt or into a storage room which may be provided in form of pockets or the like. The indicating device of the weighing device is preferably provided with means for automatically recording the indication.

Inthe accompanying drawings I have shown an example of the weighing device according to my present invention, Fig. 1 being a side-view, with parts omitted, of my new weighing device wherein the weighing device proper is moved by hand, while the material is discharged from the Weighing de-- vice by means of a container which may for instance consist of a bucket drumonto the continuously travelling belt of the conveyer. Fig. 2 shows only the weighing device proper on a larger scale together with the associated parts in a longitudinal lateral view, while Fig. 3 is a view of the device shown in Fig. 2 perpendicular to the view shown in Fig. 2. The same'reference characters indicate the same devices in the several figures of the drawings.

The travelling beltconsists of an upper part a and an under partlb. The belt is laid around the driving and guilding rollers 0 and so guided by means of the two rollers 41 and k that the material will be thrown ofi at an 7 intermediate place asindicated at g. The two its motion through aconveyer, comprising a weighing device, a travelling belt mounted on reversing rollers and adapted to serve for the supply of said material to said device as well as for the discharge of said material therefrom, means for-mounting said weighing device and said reversing rollers displaceably 'in the direction of travel of said belt for the purpose of changing at, will the place 0f weighing of said material as well as the place of discharging the same from said device.

2. A device, as specified by 01am 1, hav ng the weighing device proper and the reversing 5 rollers commonly mounted upon a travelling frame.

3. A device, as specified by claim 1, having the weighing device proper and the reversing rollers commonly mounted upon a travelling frame, said travelling frame being adapted to serve as a discharge carriage for said material.
